trisher what you seem to be wilfully ignoring is the ease with which men with purely nefarious intent, not gender dysphoria, would be able to impact on women by the action of self ID. As no hormones or surgery are a requirement just a vague commitment of "living as a woman" whatever that airy-fairy phrase means, it would be open season. You are apparently willing to risk women this way, I am not. I may take risks or relinquish rights on my own behalf, I am not entitled to make that decision on behalf of other women. Are you aware that of the self declared transwomen in prisons a greater percentage of them are guilty of sex crimes including rape than in the general male prison population? Seems rather odd you'd expect the percentages to be roughly similar.
What women get out of allowing self ID (and most trans people simply want a legal, non-medical process) is that another section of society, oppressed by the patriachy, is permitted to exist and thrive
This does not benefit women at all. What you're saying is women should put their needs behind the needs of another group once again. I think feminism should centre women and children, men have held centre stage too long. Women should have inalienable rights, including single sex spaces in prisons, hospitals, sports, communal changing rooms and showers.
